The figure shows the voltage-controlled oscillator circuit with triangular and square wave output. This circuit is the oscillator controlled by the voltage. It has the good stability and excellent linearity, and it also has the wide frequency range. This circuit has two output ends, one is the square wave output end, and the other is the triangle wave output end. In the picture, A1 is the inverter; A2 is the integrator; A3 is the comparator. FET Q1 is used to change the direction of integration. The reference voltage of the comparator is provided by the zener diode D1 and D2.
